New Build Mastic in Goodley Stock
New-build sealant joints in Goodley Stock need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Sealant work across a run of new homes
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
New build mastic in Goodley Stock, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you have leaking shower tray seals in a new home and cracks appearing as a new home settles, we can put it right, whatever the surface.
Older homes in small places like Goodley Stock often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

Surface by surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Signs you need new build mastic in Goodley Stock
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The most common problems we see are:
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Gaps opening as the house dries out and settles
Around Goodley Stock, as everywhere, new build mastic is only as good as the preparation behind it.

Advice
What new build mastic looks like in Goodley Stock
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Hurst Green station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Goodley Stock
Can you do new build mastic in Goodley Stock?
Yes. We work across London and the South East, and Goodley Stock is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Goodley Stock?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How much does new build mastic cost in Goodley Stock?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Why deal with it now?
The builder is normally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Goodley Stock can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
